IMPROVEMENT IN MACHINES FOR CUTTING HANDS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 133,686, dated December3, 1872.

To all whom it may concern: I

Be it known that I, JOSEPH H. WALKER, of the city and county ofWorcester and Common'wealth of Massachusetts, have invented 4 representsa cross-section of two rand pieces made by the machine originally used.To enable those skilled in the art to which my invention belongs to makeand use.the same, I will proceed to describe it in detail.

The machine represented in the drawing, aside from my improvements,which will be presently described, is known as Tripps Machine, for whichLetters Patent were granted to Seth 'D. Tripp, January 14, 1862. In theuse of Tripps machine in my manufacturing establishment I found it to bea very useful piece of mechanism, but I found that the rand produced wasin one essential particular defective, in that the outer edge a wasperpendicular, and consequently when the rand was applied to the heelthe corner I) had to be cut or trimmed off in order to bring the edge ofthe heel formed by the rand into the desired taper form with the otherportions thereof. This necessitates the loss of much leather and timeunder the old modes of manufacturing the heels, but by the use of theBigelow machine, patented July 5, 1870, which I have adopted, thetrimming'off was in a great measure obviated;

but still I found that in making boot-heels the corner referred to,while it was pressed in the extreme upper edge of the heel was not leftso smooth and perfect as when the 'edge a was made to conform morenearly to the shape of the heel. This led to experiments which resultedin my present improvements, and which consist in making the feed rolls AB of taper form, 'as shown in the drawing, in lieu of with horizontal orstraight faces, as in said Tripps original machine, the large part ofone roll running opposite the small part of the other roll. This-changein the form of the feed-rolls produces a great change in the rand. Inlieu of the edges a being perpendicular they arejcut with an incline orbevel, c, as shown in Fig. 3, and consequently when the rand is appliedto the heel or outer sole the outer edge of the rand is tapered inward,whereby, when the heel is compressed by the Bigelow machine, the entiresurface of the rand is pressed smooth clear to the outer sole.

It may be remarked that when the rand is applied to use with the heelthe narrow side at comes next to the outer sole, while the wide side 0comes next to the heel-lifts.

A general description of the machine is unnecessary, since the priucipleupon which it acts and mode of construction are the same as said Trippspatented machine otherwise than as above explained. It will only beadded, therefore, that the shafts of the feedrolls A'B turn in thetubular supports 0 D, cast with the frame pieces E F. The inclined knifef is supported from a frame, G, and can be set in or out by theset-screw E. This knife splits the piece of leather to form two rands,(see Fig. 3,) while the other knife 9 is fastened to cut off the piecefrom the stripof leather being cut up into rands. A suitable table is tobe arranged in front of the feed-rolls for convenience of feeding theleather and cuttin g the ran'ds.

The material is prevented from entering too far by the guide-plate h,attached to an arm, m,which can be adjusted inprojection I by means ofthe set-screw n.

The operation is as follows: The operator takes the piece of leather tobe cut into rands and passes the edge through between the feed-rollswhen the edge will be out off upon an incline by the knife g. Afterthis, at each time the leather is passed through, a strip of leatherwill be out off and divided into two rands, a crosssection of which isshown in- Fig. 3.

It will be evident to those skilled in the art that my improvement isapplicable to other 7 classes and styles of rand cutting-machines knife9 0f the inclined or beveled feed-rolls than the Tripp machine beforereferred to.
